Deckma Omd11 Manual [2021] – Newest & Premium
Under international maritime law (MARPOL Annex I), 15ppm bilge alarms must be calibrated and checked regularly.
Under International Maritime Organization (IMO) regulations, the 15 ppm bilge alarm must be periodically checked for accuracy.
This article serves as an extended technical companion to the official manual. We will dissect everything from the basic measuring principle (light obscuration) to advanced parameter settings, alarm resets, calibration procedures, and common fault finding. Whether you are a newly promoted Second Engineer or a seasoned veteran, this deep dive into the OMD-11 will ensure you are prepared.
Deckma OMD-11 is a legacy bilge alarm unit designed to monitor oil-in-water concentrations in marine environments, specifically to ensure compliance with IMO Resolution MEPC.60(33) standards. Core Function & Features deckma omd11 manual
Weighs approximately 3.5 kg with an IP 65 protection rating. Installation & Operational Essentials
A near-infrared light source passes through the sample water.
Pre-alarm triggers at 2.5 %/m. Main Alarm triggers at 5.0 %/m. (These values are adjustable but rarely changed due to class approval). Under international maritime law (MARPOL Annex I), 15ppm
: Proper function is verified using a Formazin polymer reference standard (typically 4000 FTU diluted to specific requirements) to ensure the monitor remains within the required accuracy limits.

Note: This document is a comprehensive reference guide compiled from general technical knowledge of the Deckma OMD-11 system. For official certification and specific calibration data, always consult the original manufacturer's manual and manuals provided with your specific serial number.
• Ensure sample piping flows upward; bleed air from line.• Verify the integrity of the chassis ground strap. Regulatory Compliance and Recalibration We will dissect everything from the basic measuring
While ship crew can perform routine zero-point adjustments using clean water, require testing with certified calibration fluids. Many port state control officers look for valid calibration stickers. If your OMD-11 fails to hold its zero calibration or suffers from severe optical degradation, the measuring cell must be sent to an authorized Deckma service center or replaced with a modern, type-approved equivalent system to keep the vessel compliant.
: Designed to minimize false readings caused by non-oil contaminants like iron oxide, showing only 2 ppm for substances that older monitors might misread as 15 ppm. Dual Alarms
The Deckma OMD-11 is designed to fulfill the baseline requirements outlined under the International Maritime Organization (IMO) . It incorporates an advanced optical scattered light measurement system featuring an enhanced solids-suppression matrix. This technology prevents false alarms triggered by non-oil particulates such as rust, iron oxide, or mud. Operational Specification Measurement Range 0 to 30 ppm (Trend indication scales up to 50 ppm) Accuracy / Linearity
The Deckma OMD-11 is a high-precision 15 ppm bilge alarm monitor designed to improve the reliability and operation of oily water separator (OWS) systems. Meeting the requirements of IMO Resolution MEPC.60(33) , the OMD-11 utilizes advanced solids suppression technology to distinguish between oil particles, solid particles, and water turbidity.
